Q: What makes a great designer?
A: It is so important to be light on your feet, inquisitive and interested in being wrong. You have that wonderful fascination with the what if questions, but you also need absolute focus and a keen insight into the context and what is important - that is really terribly important. Its about contradictions you have to navigate.
Ever wonder about Apple's design philosophy? His name is Jonathan Ive.
If you like this kinda stuff like I do, take a peak at the documentary Objectified (I watched it on Netflix), about how everyday objects around us are designed. It's a rather long documentary, and I got bored at parts of it; so feel free to skip around it.
